DNA containsnucleobases, sugar and phosphate. Removal of which among these from a DNA sample will not significantly affect the length of DNA?a)Nucleobasesb)Sugarc)Phosphated)None of the aboveCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

NUCLEOBASE(it is base pairing between nitrogen bases i.e A ,T,G,C) therefore it does not affect the length of DNA where as sugar phosphate bond is the back bone of DNA therefore they both affect the length of DNA

Answer

Option A is correct
because sugar and phosphate form the backbone of polynucleotide chain and nucleobases means nitrogenous base are branch out from it so removal of it will not affect the length of DNA

Answer

Nucleobases, also known as nitrogenous bases  are nitrogen-containing biological compounds that form nucleosides, which in turn are components of nucleotides, with all of these monomersconstituting the basic building blocks of nucleic acids. The ability of nucleobases to form base pairs and to stack one upon another leads directly to long-chain helical structures such as ribonucleic acid (RNA) and deoxyribonucleic acid (DNA)....

Answer

Removal of Nucleobases from DNA

Nucleobases are the building blocks of DNA, which are responsible for carrying genetic information. The four types of nucleobases present in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T). The removal of nucleobases from DNA will not significantly affect the length of DNA because:

- DNA length is determined by the number of nucleotides, not the type of nucleobases.
- Each nucleotide in DNA consists of a sugar molecule, a phosphate group, and a nucleobase. The sugar and phosphate molecules form the backbone of DNA, while the nucleobases are attached to the sugar molecule.
- DNA strands are held together by hydrogen bonds between complementary nucleobases. Adenine pairs with thymine, and guanine pairs with cytosine.
- Therefore, if a nucleobase is removed from one strand of DNA, the complementary nucleobase on the other strand will also be removed, resulting in a break in the DNA strand.
- However, the length of the DNA strand will remain the same, as the sugar and phosphate molecules are still present.

In conclusion, removal of nucleobases from DNA will not significantly affect the length of DNA as it is determined by the number of nucleotides, not the type of nucleobases.

Answer

DNA is maid by many compound but significantly nucleobase is important part they made long chain and joint with sugar and make DNA that's reason

Answer

The DNA structure is like a long twisted ladder.The sugar and phosphate group form main backbone(and determine the length).But the neucleobases are laterally attatched to the backbone and act as the 'rungs'(steps) of the ladder and therefore cannot determine the length.(How can the length of a ladder change if we remove it's rungs!!)

Answer

Nucleobases..
